Choose solid trays with drainage holes for growing microgreens, sprouts, or bareroot transplants and those without drainage holes for bottom watering. Trays are required if growing in Pro-Tray flats. Available in small and case quantities. To compare products and view product compatibility, see our Support Trays Dynamic Comparison Chart (at right).
